Walker, the 40-year-old actor who played Brian O'Conner in the popular car racing films, was the passenger in a vehicle driven by a friend before they both lost their lives in a crash. After the film resumed shooting last month, the "Fast & Furious 7" Facebook page posted a message about his brothers Caleb and Cody Walker filling in for their late brother.

"Donate….. Support guys….," Gibson wrote on Instagram. "@codywalkerroww moved to LA to keep his brothers charitable organization going!!"

Gibson posted a photograph of the late actor with the quote, "When you put good will out there, it's amazing what can be accomplished."

Last month the "Fast & Furious 7" Facebook page posted a message about Caleb and Cody Walker filling in for their late brother.

"Paul had already shot his dramatic scenes and most of his action for Fast & Furious 7, and it's among the strongest work of his career," the Facebook message reads. "We have resumed shooting and now welcome Paul's brothers, Caleb and Cody, into our Fast family. Caleb and Cody are helping us complete some remaining action for their brother and fill in small gaps left in production. Having them on set has made us all feel that Paul is with us too."

The message also highlighted the importance of family in the film.

"The Fast & Furious saga is about family," reads the post. "The characters are connected by the bond of family, and it is how all of us who have worked together for more than thirteen years feel about each other. It certainly defines how we feel about our fans."
